The thermoplastic polymer material of the first strand may at least partially adhere to the base layer. In another aspect, the article may include a first embroidered area and a second embroidered area. The first embroidered area may have a first degree of a mechanical property, and the second embroidered area may have a second degree of the mechanical property. The first degree of the mechanical property may be different than the second degree of the mechanical property.
Abstract:

Abstract:
A high temperature resistant textile sleeve and method of construction thereof is provided. The textile sleeve has a flexible, tubular knit wall of thermoplastic yarns. The yarns are tightly knit with weft knit stitches extending along a circumferential direction about the tubular knit wall to provide a substantially smooth inner surface and a substantially smooth outer surface. The yarns are knit in a tricot stitch pattern, wherein the tricot knit stitches extend along a circumferentially direction of the sleeve wall.
Abstract:
A system (1) for controlling the feed of a yarn to a textile machine or a metal wire to a coil winder or a similar machine, the yarn or wire unwinding from its own spool and cooperating with a rotary member associated with its own rotation actuator (2) before being directed to the machine, the yarn or wire having its own characteristic value of tension and/or speed and/or quantity during this feed, the rotation actuator (2) comprising a stator and a rotor acting on an exit drive shaft (13) and being piloted by its own piloting means, the rotary member about which the yarn or wire winds being keyed onto the exit drive shaft (13), the control system comprising:means (4) for continuously measuring an angular position of the drive shaft of the actuator (2),comparison and command means (5, 8) connected downstream of the measurement means (4), to compare an instantaneous parameter correlated to the measured angular position of the drive shaft (13), with a corresponding predetermined parameter relative to a prefixed characteristic value of the yarn or wire, and to feed command signals to piloting means (3, 6) for the actuator (2) such that the instantaneous parameter conforms to the predetermined parameter, so as to obtain the required characteristic value of the yarn or wire fed to the machine.
Abstract:
An apparatus (1) is provided to control the weight of fabric produced by a textile machine (2), comprising weighting means (11) of every single fabric piece directly associated to the textile machine dedicated to the manufacture of the same. A procedure is also provided to control the weight of the fabric produced by a textile machine comprising a weighting stage of every single fabric wounded or folded, near the textile machine dedicated to the manufacture of said piece, and to apply to every manufactured piece a printed label suitable to provide at least specific data concerning the piece weight.
Abstract:
A single-cylinder circular machine for knitting, hosiery or the like, with a device for actuating the cutter mounted on the dial comprises: a needle cylinder, which can be rotationally actuated about its own axis; a dial, which is arranged above the needle cylinder and is supported so that it can rotate about its own axis; and a cutter for cutting the yarns, which is mounted coaxially on the dial and is provided with cutting teeth arranged around its own axis. The machine has a device which comprises an actuation for the cutter with a rotary motion about its own axis with a rotation rate which can be diversified from the rotation rate of the needle cylinder, in order to vary the length of the trailing portion of yarn that lies between the last needle of the machine taking up the yarn and the blade cooperating with the cutter in cutting the yarn.
Abstract:
A continuously weft-knitted three-dimensional fabric cover having sutures to accommodate its three-dimensional format in which each suture defines a straight line or a series of straight lines joined end-to-end, each straight line lying at an angle of between 0 and 50 to the course-wise direction of the fabric.
Abstract:
A method and relative equipment, applicable to a knitting machine for the production of collars and similar articles, for restraining, during knitting, the terminal portions of cut thread (12, 13) protruding from the edge (5) of said collars by inserting them inside the courses of stitches which compose them. The means for inserting (16) said thread ends (12, 13) between two successive courses of stitches (2,3 and 3,4) while knitting, comprise at least one nozzle (27, 37) producing a fluid current(22, 32). One of the nozzles (37) may be able to rotate from a first direction (A) of catching the end portion of thread to a second direction (B) aligned with the courses of stitches during the knitting process. Means for inserting can also comprise a first nozzle (27) producing a first jet of fluid (22) for catching the thread end and a second nozzle (37) producing a second jet of fluid (32) for inserting it between two courses of stitches. The restraint of the end portions of thread (12, 13) is carried out automatically while knitting, with considerable advantage compared to manual restraining as well as mechanical inserting, thanks to the precision of fluid jets (22, 32) which are preferably of air or water.
Abstract:
In knitting parts (a guide, needle, tongue, sinker, separator, jacquard guide needle and the like) of a knitting machine, a covering of a hard carbon film 15 of a preset film thickness d on a surface of a portion of a parts base material 10 frequently contacting with knitting yarn and, at the same time, a film thickness changing area 16 where the film thickness of the hard carbon film decreases gradually is formed from an area where the covering of the hard carbon film 15 of the preset film thickness d is formed to an area where such a covering is not formed. A ratio (L/d) between length L of the film thickness changing area 16 toward a film changing direction and the preset film thickness d of the hard carbon film 15 is controlled to be at least 5:1.
Abstract:
An automatic stitch cam adjustment mechanism for a circular knitting machine is disclosed. The knitting machine includes a plurality of knitting needles supported in a rotating needle cylinder for vertical movement parallel to the axis of rotation of the needle cylinder. A plurality of cam support brackets surround the needle cylinder, and a plurality of stitch cam support members are slidably mounted on the cam support brackets for vertical movement thereon. Stitch cams are mounted on the stitch cam support members for engaging the needles and lowering the needles to a loop formation point. A drive motor is connected to each of the stitch cam support members for moving the stitch cam support members up and down. Sensors are included for (1) measuring the position of the movable support members along the vertical path of movement, (2) detecting the rotational speed of the needle cylinder, and (3) measuring a feeding characteristic of the yarn such as yarn feed tension or quantity. A controller is operatively connected to the drive motors and sensors for comparing each of the sensed values with a predetermined knitting machine operating standard and actuating the drive motors for adjusting the stitch cams as needed.
